Abstract

A supercapacitor desalination cell (16) is provided. The cell (16) includes electrodes (24, 26) formed of conducting materials that are configured to absorb ions in a charging state of the cell and desorb the ions in a discharging state of the cell. The conducting materials comprise conducting composites. An insulating spacer (28) is disposed between the two electrodes (24, 26) and is configured to electrically isolate one electrode from the other. Further, the cell (16) includes a first current collector (30) coupled to the first electrode (24) and a second current collector (26) coupled to the second electrode (26) . Further, an energy recovery converter may be operatively associated with the cell and configured to recover energy released by the cell while transforming from a charging state to a discharging state. The converter is configured to transfer at least a portion of the recovered energy to a grid in the discharging state of the cell.
